Another DH cirrus moth!

It sounds like you need something like this



Better to buy them a bit longer than you need and then cut them down if you are not sure on length.( sorry that was a very obvious thing to say) I use a similar screw on the Redfin in my DH60 .As the cowling is removable I start and adjust compression before fitting the cowling so no need for a hole in the top. You just have to remember to have an Allen key and not loose it when you're flying...not as easy as it sounds I now carry several

If you have problems getting them PM me and I can get them here and forward them onto you

Hi Guys!!!


some (5-6) glide test on my Gipsy Moth. seems to is a little nose heavy, but is hard to know, as was almost 0 wind. but have 3 videos....



in this one... a bad launch!



and on this one, add more up on elevator....




Chris: on your model, what patern you used, Right power left Glide?

The glides look good to me...I'd go for low power flights next.

Always go left under power with a free flight power model. If you go right under power the gyroscopic precession will cause the model to spiral in. Going left, the gyroscopic precession will keep the nose up. The glide turn is up to you, choose whichever direction helps you to trim the power part of the flight.

As Andy says left power and the glide is up to you.

Mine has some right rudder so it glides right but turns left under power due to the torque of the motor. The right rudder means it needs less side thrust than it would with a left, left pattern where the side thrust has effectively cancelled out the torque from the motor and the rudder is providing the input for the turn

Again Andy is a better judge but the glide is not bad and worth a low power 'hop' . It won't glide anything like the sport models you are used to.

Some low power will help you work out how it's going much better and video 3 looked pretty good to me too, The best I've had mine flying at Port Meadow the glide is not 'floaty' its quite positive. A forward cg is the way to go, it gets a bit unstable as the cg moves back

Hi Andy and Chris! thanks for support!

will keep in mind your advice! for me this is new, as it looks as a stone flying! jejeje, yes, i use to fly Vic Smeed models and some vintage designs as Diamond Demon or Playboys...... and if forget to light the fuse... can say ciao to the model!!! jejej

Don't think that I am jealous, just because I have nowhere to fly F/F and am too old to chase them anyway!

Some very nice flights Rodrigo in what looks like lovely conditions, the Ballerina landing almost at your feet

A very impressive set of maiden flights, thanks for sharing

Very nice Rodrigo, thanks for sharing. You're certainly blessed with a good wide open flying site and perfect weather....I'm envious!

You're a lucky so and so Rodrigo

Nice model Rodrigo.

A brass compression screw would soon wear into a mushroom shape where it contacts the contra-piston which would make it very difficult to remove.

Could you not knock the pin out from the original compression screw and file a slot for a screwdriver or if you do not wish to damage the original too much what about replacing the pin with a very short pin that just projects a little and adjust it with a tube with a couple of slots and a big handle?
